A device for removing floating material from a liquid, especially from sewage, has at least one sieve element shaped like a filter basket, for example, that in a front side has an inlet opening through which liquid can flow into the interior of the sieve element. The device is equipped with a drive so the sieve element can rotate around a rotation axis. A collection device is arranged within the sieve element for collecting the liquid and/or floating material, in which case the collection device is attached to a pumping-out device for the liquid and/or the floating material. A process for removing floating material from a liquid, especially from sewage, uses a sieve device that contains at least one sieve element that may be shaped like a filter basket, for example, and is equipped with a drive so it can rotate around a rotating axis. Liquid and/or floating material is collected with the help of a collection device arranged within the sieve element for subsequent withdrawal from the collecting device with a pumping-out device.

Device and process for removing floating material from a liquid

A method for transferring heat includes flowing a wastewater through a tank and flowing a fluid through a heat exchanger having an outer surface. The method further includes aerating the wastewater to produce a convective flow, contacting the outer surface of the heat exchanger with the convective flow to exchange heat, and cleaning the outer surface of the heat exchanger with the convective flow. A system for transferring heat includes a tank, a heat exchanger with an outer surface disposed in the tank, and a fluid flowing through the heat exchanger. Wastewater located in the tank flows over the outer surface of the heat exchanger, and a diffusion pipe disposed in the tank provides air into the tank to produce a convective flow in the wastewater.

Method and device for transmitting heat between waste water located in a tank and a fluid

An apparatus serves for removing fine material to be screened from waste water. The apparatus includes a sieve grate () and a detaching device (). The sieve grate () is cylindrical, and it is rotatingly driven. The sieve grate () allows for waste water to flow from its interior towards its exterior. The sieve grate () includes a supporting body () and a mesh sieve (). The supporting body () is located at the exterior of the sieve grate (). The supporting body () is made of a perforated sheet metal including comparatively large openings (). The supporting body () provides for resistance and stability of the sieve grate (). The mesh sieve () is located in the interior of the sieve grate (). The mesh sieve () forms a separation surface () for the material to be screened. The mesh sieve () includes meshes of a comparatively small size. The mesh sieve () is fixedly connected to the supporting body (). The detaching device () is arranged outside of the sieve grate (). The detaching device () includes a plurality of nozzles (). The nozzles () are designed and arranged to spray water from outside of the sieve grate () towards the interior of the sieve grate () in a way to detach material to be screened adhering to the inner surface of the sieve grate ().

Apparatus for removing fine material from a liquid

An apparatus for removing material from a liquid flowing through a channel includes a sieve grate, a screw conveyor and a detaching device. The sieve grate has an inflow side, an inner side and an outer side. The sieve grate is designed to be cylindrical and to be rotatably driven. The sieve grate is arranged at an inclined orientation to be partially submerged in the liquid. The sieve grate at the inflow side includes an open face. The sieve grate at the inner side includes a plurality of guide plates. The sieve grate includes a shaping carrier element. The sieve grate includes a mesh fabric, the mesh fabric being designed and arranged to form a separation surface for the material. The screw conveyor includes a housing. The screw conveyor includes a driven conveying screw. The screw conveyor is coaxially arranged with respect to the sieve grate. The screw conveyor in the region of the sieve grate includes a feeding hopper for the material, the feeding hopper having a bottom side and including a majority of openings located in the region of the bottom side. The detaching device is arranged at the outer side of the sieve grate and above the feeding hopper in a stationary way. The detaching device is designed and arranged to detach material which adheres to the separation surface from inside of the sieve grate.
